 Msubsup are broken up in the semantic tree into explicit subscripts and superscripts if advisable.
 
-Stick with alternative 2 for now. Look into prime, etc.
+We will stick with alternative 2 and add a collapsed attribute. Example is now here:
+ 
+```html
+<math>
+  <msubsup type="subsup" role="latinletter" id="4" children="0,1,2" collapsed="(4 (3 0 1) 2)">
+    <mi type="identifier" role="latinletter" id="0" parent="4">a</mi>
+    <mi type="identifier" role="latinletter" id="1" parent="4">b</mi>
+    <mi type="identifier" role="latinletter" id="2" parent="4">c</mi>
+  </msubsup>
+</math>
+
+```
+
+Still to do: Look into prime, etc.
